an honest review, so to begin with, i wasnt even planning on buying a new mattress at the time, it was on a whim that i went into the shop as hadn't looked at new beds for a loooooong time, so thought why not, probably wont be very good, but the sales team were excellent and taking the time, which was well over an hour, going through a lot of bed options, and only going to this one as a "i do have one more to show but its a lot more money" option... but it was so comfortable the second i got on it in the shop compared to the others, which granted were half the price! from paperwork to delivery and the first nights sleep, its bliss! trying in the shop means you know what your buying before you even get it, and cant technically be disappointed. now for the details:- Its THICCCCCCK! this is a very deep and heavy mattress, 40+cm, so know your sheets are going to fit before buying you aint going to be rotating or moving it often as it is heavy, just move yourself around the bed for bedding in sleeping possitions to keep it fresh... you sink into it like a marshmellow, then stop when it thinks your possition is correct, and it is, your supported where you need it, free where your not the Igel cooling, i cant really comment on tooo much as its not been hot nights yet to test, but its certainly not like other memory foams iv had before where the heat bounces back and it feels sweaty what down sides can there be other than those that people make up due to not doing reaserch before they get it.... HEAVY, THICK, kinda pricy you spend half your life in bed, why not have it in the most comfort you can possibly get, its no different than people spending 1000s on sofas and tvs, they only do 1 job, as does this, but it does its job dam well! there really isnt much that can be said for this mattress, if you can afford it, get it! simple
